Something about this manga gives me a bad feeling. The author tried to make the protagonist a kind of heir to the hero, who in turn saved the world and was incredible in every aspect. So much so that the protagonist's greatest desire is to be like this hero. In fact, this is repeated so many times throughout the story that even other people are inspired by the hero. In other words, there's no room for doubt: this hero is truly the hero in every sense.
So far, so good—the protagonist being inspired by someone he admires is normal. But then come the heroines. We don't know what relationship they had with the hero, nor what feelings they harbored for him. But when they meet the protagonist—who looks exactly like the hero—they decide to help him. Still, so good: he got incredible mentors…
But then things start to get very strange.
They have a romantic interest in the protagonist, and even though they didn't seem to show anything for the hero before, sometimes it seems like they had a platonic love for him. It's strange: it seems that their interest in the protagonist exists only because he resembles the hero. It's as if they wanted the hero back, not the protagonist himself.
Then a new objective emerges: to find the diary the hero left behind—the "One Piece" of this story. But what is their interest in this? What is their goal? Is the protagonist just a substitute for the hero in their eyes? Is he a real romantic interest? Does he have his own personality or is he just playing the role of "heir"?
And speaking of personality: the protagonist has an impressively cold heart. He doesn't seem bothered, or even curious, about why on earth they are so intent on him or on discovering the memories of the former hero…
